Guides / Peptides
Peptides
Peptides are short amino-acid chains used to communicate specific skin goals — firmness, calm, brightness, or repair. Understanding type and stability matters more than marketing names.
Common families
Signal peptides encourage matrix-related pathways; carrier peptides deliver trace elements; neurotransmitter-inhibiting peptides are positioned for expression-line care. Each needs different supporting chassis.
Stability and delivery
Many peptides dislike high heat, extreme pH, or strong oxidizers. Prefer cool-down addition, suitable pH windows, and packaging that limits air and light when the supplier recommends it.
How to choose
Match claim to evidence package, check recommended %, and confirm compatibility with acids, retinoids, and preservative systems already in the formula.
